yf 'y Unrrnn STATES PATENT JULIUS MANNEBAGH, OF NEW YORK, N. Y.

Specification forming part of Letters Patent No. 133,653, dated December3, 187:2.

To all whom it 'may concern:

Be it known that I, JULIUs MANNEBAOH, of the city, county, and State ofNew York, have invented a new and useful Improvement in Miter-PlaningMachine; and I do hereby declare the following to be a full, clear, andexact description thereof, which will enable those skilled in the art tomake and use the "same, reference being had to the accompanying drawingforming part of this specication, in which drawing- Figure 1 representsa vertical section of this invention inthe planea' fr, Figs. 2 and 3;Fig. 2 is a horizontal section of -the same in the plane y y, Figs. 1and 3; Fig. 3 is a rear view of the same; and Fig. 4 is a horizontalsection in the plane y y, when the miter-board has been removed from themiter-plati'orm.

Similar letters indicate corresponding parts. This invention consists inthe arrangement of two pla-nes fitted between vertical guides, andconnected to foot levers or treadles in-com- Vbination witha platformcontaining adjustable abutmcnts and with a ruiter-board, which can beplaced on said platform in such a manner that when the miter-board isput on my machine can be used for beveling moldings for picture-framesor other articles, first on one and then on the opposite end; and whenthe miter-board is removed my machine can be used for beveling moldingsfor cornices and other articles7 the abutments on the miterplatformbeing adjusted to the desired angle. The throw of the footdeverswhichserve to operate' the planes is reduced by interposing between them andthe planes secondary or reducing levers.

, In the drawing, the letter A designates a frame, which is providedwith two pairsof tothe planes however, but they are attached by links dto intermediate levers D D, which swing on pivots c c secured in theframe A and which connect by links f f with the planes, theconnecting-points between the links d d and the intermediate levers D Dbeing between the fulcrum-pins e c and the connectingpoints of the linksff, (see Fig. 3,) so vthat the motion of the treadles is multiplied, anda comparatively small throw of said treadles imparts to the planes therequired motion. This arrangement is necessary, since for cornices andother articles moldings are used which are eight. inches high or more,and in order to impart to the planes the stroke required to act on suchmoldings the motion of the treadles has to be multiplied, else themachine would becomc very inconvenient to op crate.

The Inoldings to be exposed to the action of the planes B B are placedon the platform E, which is provided with two miter-abntments, g g, eachof which is composed of two parts connected by a hinge-joint, 1I., aslotted arc, i, and set-screw j. (See Fig. 4.) By this arrangement I amenabled to adjust the faces of the miter-abutments to different anglesto correspond to the angles at which it is desired to cut the ends ofthe moldings. On the platform E may be placed the miter-board F, whichis provided with one or more steadypins to keep it in position, and onthe surface of which are secured stationary abutments k k. (See Fig. 2.)By means of these abutments the ends of moldings are presented to theaction of the planes, so that the same will be cut` at angles offorty-five degrees. For

different angles different miter-boards may be provided.

By these means a machine is obtained which serves to cut the ends of allsorts of moldings to any desired angle with ease and facility.

What I claim as new, and desire to secure by Letters Patent, is

The intermediate levers D D, in combination with the foot-levers G C,planes B B, miter board or platform E, and frame A, all constructed and.operating substantially as set forth.
